TEMPORARY BINDER Application filed January 25, 1929. Serial No. 334,897.

This I invention relates to a temporary binder. I

An object of the invention is to provide a temporary binder which may be 'inexpene .;5 sively manufactured and which will be efiicientand practical in operation;

;I A more specific object is to provide a binder including snap. acting ring shaped members for holding the sheets in'the binder, and in .10 which all of the'parts are of simple, and

easily and in which I have shown merelya preferred I form of embodiment of the invention Fig. 1 is'a' longitudinal sectional view through a binder constructed in accordance with this invention, a section being taken sub: stantially uponthe plane of line II of Fig. '2; i r Fig. 2 is'a top planview ofthe structure seeninFig.1. 1' 1 f Fig. 3 is an enlarged transverse sectional view taken upon the plane of line III--III L f of Fig. 2. l

I I

Referring to the drawings for. describing 2 but illustrating a slightly modified'form of in detail the structure illustrated therein, the reference character L indicates what may be termed the back or binder portion of a book, said back preferably carrying at its opposite sides the usual hinged'covers 1 and 2.

The covers 1 and 2 may be parts of a single continuous piece of fibre board if desired, in

which instance the intermediate portion of said PIECE of fibre board will extend across and comprise,or form, the back or binder portion L.

The binder portion is preferably provided with depressions or seats as 8 adjacent its opposite ends for receiving the sheet retain- .ers Gr therein, and these seats are covered by spring metal plates H which have openings as 4 through which portions of the sheet retainers G movably extend.

These parts at opposite ends of the back are of identicalconstruction and a detailed description of one will apply to both as follows: Y

The sheet retainer consistsof two separate members as Band 6. These have stemportions as and 8 lying parallel to each other and ring portions as 9 and 10 continuing laterally in opposite directions from one'end of the stem portions and being curved around so that when their outer ends are'together. as I in Fig. 4 they will'complete a circle within which the sheetsas 11 may be retained in a manner well known to this general type of binder, it being understood that the sheets are provided with the customary apertures as 12 therein for looselyreceiving the ring shaped members 9 and 10 therethrough. I r The depression or seat 3 in the back is so arranged andproportioned with respect to the stems 7 and Sand withrespect to the plate H that the walls .of said seat co-operatewith the under-surface of the plate to provide a snug hearing within which the stems are capable, of rotating under friction whenever the ring shaped portions 9 and 10 are manually swung between the positions Figs. 3 and 4. The spring plate exerts a continual pressure against the stems holdingthestems in turn ressed against the bottom and side walls 0 the seat so that'thestemsare fric It is further suggested, as seen particularly in Fig. 3, that if desired the stems. may be provided with projections or other suitable formations as 15 co-operative with partsas 16 provided upon the spring plate to serve as snap acting means to yieldingly hold the ring members in either-of. their; extreme positions.

In assembling these parts it is simply necessary to lay the stems of the sheet retainers in the seat 3 with the parts 13. and let in properengagement, then apply the spring plate in position over theseat with the ring shaped" extensions 9"and 10'projecting through the openings 4 of the plate, and

finally. fasten the plate as by means of the rivets or other fastening devices 17 illustrated, it ibeing noted! that the devices 17 are removed from the region of the stems so that the portion of theplate engaging the stems is permitted a suitable degree of spring flexing movementto accomplish the purposes above referred to;

The position ofthe ring-shaped. extensions 9- and: 10 extending through. the openings 4 of the plate will prevent any longitudinal.

displacement of. the stem portions, the openings: 4 being. of course suitably elongated however to permit unobstructed swinging movement of the extensions between the positions Figs;3and4.. q

The abutting tree ends of the ring-shaped extensions 9' and 10 may if desired be provided with co-operative snap latching elements adapted to-interengage with eachother for holdingsaid ends together, and the drawing therefore suggests that the member 9 maybe provided with; a headed extension 18 for engagement within a spring socket 1-9 of the member 1 0, said. parts constituting a; latch of thetypecommonly known;as glove f-astenerf. f

r'lhe springplates HH are preferably set into shallow depressions20 provided in the back sothat the upper surface. ofthe back will be smooth. and unobstructed throughout. the modificationFig. 5 the structure is identicalwith that already described except that the toothed engagment betweenthe stems of the sheet. retainers is omitted and said stems are separated from each other and held in separateseats so that. the two ring shaped members are. capable of independent movement with respect to each other, as illustrated in Fig; 9;

Inthe modification-Figs. 6 and 7 the structure is again the sameexcept that here each sheet retainer consists of only asingle ring.

shaped member. The stem as 21 ofthis retainer is received within a seat or depression 22 provided in the back and is held therein under friction by the spring plate H as heretofore. (Jo-operative parts as 15 and 16 are provided between the stem and the plate for holding the stem in its opposite extreme positions. The outerend of'the ring shaped extension 23 of this retainer is intended to move into and out of an opening as 24 provided through the plate H at a point removed from the stem, and if desired said end of the extension may be arranged to rub frictionally againstthe wall of said opening and be provided with a notch 25 therein for yieldingly interlocking with: said. plate" in the manner as clearly seen in Fig. 7 thus tov afior'd a more permanent means of. holding the sheet retainer'against accidental movement tosheet releasing position. The ring. shaped extension 23 will of course be sufiicientlyresilient to permit its yielding engagement withthe plate to accomplish this result.

By reference to the illustration Fig. 8 it will be seen that the depression or seat. 3 for receiving the stems? and 8 and the ring shaped portions 9 and lOlmay if desired consist of a hole as'26'ofappropriateshapeextending. entirely through a separateback or filler member as 27 which is fitted into;: a main. back or hinder portion L, said binder portion being in this case shaped to provide: a channel as 28 throughout itslength of a sizetosnugly receive and? hold the: filler 27 substantially the manner as shown and described more fully in my pending application Serial No. 272,578, filed April 25th,. 1928. The filler 27 may be cemented, riveted, or

otherwise held in a. substantially rigid position within thechannel 28, andv the upper flat surfaceportions of the binder L. underlying the holes 26 will of course constitutesbottom walls for closing the lower ends of'the holes 26 thereby constituting them as1 seats for proper co-operative action with thestems and ring shaped portionsin the samemanner as-above described with respect to: previous figures.

A separate filler as 27 acts. as a're-inforcing element for the binder portionL and at thesametime enables the outer surface ofsaid binder portion to-be made perfectly smooth and uniform throughout. its extent. The metal plates H may be riveted toathe filler 27, thus even avoiding appearance of the rivet heads exteriorly of the binder L if desired,

.with projections or other suitable forms as 15 and 16 above described for producing snap actingmovement of the sheet retainers in the same manner as recited with reference to the previous figures.

As many changes could be made in this construction without departing from the scope of the invention as defined in the fol lowing claims, it is intended that all matter contained in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative only and not in a limiting sense.
